Communication with SPI slave (Kinetis MKW24D512)

diaskuo — Sun, 24 Jan 2016 13:54:52 GMT

Hi everyone,

I am a newbie here, and my English is not very good. Sorry about that.

I have a SPI slave (Kinetis MKW24D512VHA5) connected to a MIPS host processor via SPI.

I would like to access and control the SPI slave by ZigBee Test Client (ZTC) protocol on host.

How can I drive and communicate with the SPI slave?

Does anyone have any example project on Linux host to communicate the SPI slave via SPI?

Best Regards,

Dias

Hello Dias,

You need to modify some macros to configure the ZTC over SPI in a project.

First, enable the SPI interface by modifying the macros commented as /* Stub functions*/ in the PLM/Interface/SPI_Interface.h file.

Then, define the gZtcCommInterfaceType_d macro as gCfgSPIInterface_d in the ZTC/Interface/ZTCInterface.h file.

I hope this helps.

Best regards,

Earl.

Hi Earl, thank you for your reply.

I found below descriptions on page 59, Chapter 5, ZTC Frame Format, BeeStack BlackBox ZigBee Test Client (ZTC), BSBBZTCRM.pdf.

All communication with the ZTC protocol can be accomplished using two interface

- A three wire UART connection (...)

- A three wire I2C connect (...)

Would you please tell me can ZTC support over SPI?

BeeKit shows a warning message window when I export my project enabled both Keyboard (KB) and SPI modules.

Do I need the KB for a ZigBee coordinator device?

An open system (no security) Wi-Fi connection flow between a wireless client and an access point (AP) is probe request (req)/response (rsp), authentication req/rsp and association req/rsp.

Where can I find a ZigBee connection flow between a coordinator and a end device?

I would like to know which ZTC commands do I need to send out from host to the coordinator to communicate with ZigBee end device via SPI?

In my case, would you please give me some examples for forming a ZigBee network and toggling a light using ZigBee technology?

Thank you for taking your time to read my questions.

Best regards,

Dias

Hello,

This is already answered in the thread Forming a ZigBee network by ZigBee Test Client (ZTC).

Best regards,
